Linux kernel source tree

Record statistics for contention upon the writeback serialisation lock that prevents racing writeback calls from causing each other to interleave their writebacks. These can be viewed in /proc/fs/netfs/stats on the WbLock line, with skip=N indicating the number of non-SYNC writebacks skipped and wait=N indicating the number of SYNC writebacks that waited.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
